Pursuant to Schedule 3 of the Customs (Management and Control) Act, the importation of radio and television transmitting equipment, including walkie-talkies, is prohibited unless authorised under a licence issued by the Minister of Communications.

The Act No. 5 of 1968 - External Trade Act grants the Minister authority, under Art. 5, to regulate the export of goods through orders published in the Gazette. These orders may prohibit exports without a licence, impose restrictions, or set conditions for exportation. Such orders take effect upon publication and automatically cancel previously issued licences, requiring the Permanent Secretary to issue new licences in compliance with the updated provisions.
Art. 6 empowers the Permanent Secretary to issue licences for export-restricted goods, provided the export does not undermine any trade agreements or arrangements related to internal or external trade or currency approved by the Government. Licences are denied if the export poses risks to these agreements or arrangements.
As of 2023, these requirements only apply to radio and television transmitting equipment, whose exports are allowed only with a licence from the Minister of Communications.

According to Art. 4 of the Statutory Instrument 10/2002, the equipment mentioned in Art. 4.2 must receive a type approval certificate from the regulatory authority. This includes cellular telephones, cordless telephones, fax machines, GSM machines, mobile radios, modems, wireless remote devices, PABXs, pagers, radio receivers and transmitters, satellite earth stations, telecommunications switching equipment, telephone instruments, telex equipment, other equipment emitting a radio signal and any other customer premise equipment to be attached to any part of a licensed telecommunications network.
According to the Caribbean Cooperation for Accreditation (CCA) standards, foreign businesses must pass an accreditation by accredited laboratories that have Mutual Recognition Agreements (MRAs) with counterpart bodies. Test results from accredited laboratories, which are parties to a given MRA, are automatically accepted. The CCA is based on principles of cooperation and collaboration among the recognised National Accreditation Bodies (NABs).
